Question

Sovle a triangle when A=40°, C=70°, and a=20.​

Answer 1

Answer: B = 70°, b = 29.2; c = 29.2

Step-by-step explanation:

sum of angles in a triangle is 180

40+70 +X = 180

X is the last angle

110+x=180

x= 180-110 =70

A= 40°

B= 70°

C= 70°

the triangle is Isosceles triangle meaning two sides are equal , angle B = angle C
